3D model description

Le remix du support que j'ai fait precedement ne me convenait pas car il ne me permettais pas de demonter le moteur rapidement.
J'ai donc creer celui ci. Il permet d'avoir le moteur dans une bonne position , qui ne gene pas le mouvement du telescope en altitude. Il permet egalement d'enlever le moteur rapidement ou de le " debrayer " pour faire une mise au point manuelle.
J'ai pris le parti de ne pas mettre de vis " tirante " pour tendre la courroie car finalement ca ne sert a rien , sauf a trop tirer sur l'axe de mise au point du telescope. La mise en tension a la main est bien suffisante. (Si toutefois vous desirez une vis tirante , j'ai dessiné les pieces pour et je vous les fournirai a la demande).
Pour la molette de mise au point j'ai utilisé des vis chc M3 ( pensez a passer un taraud avant ) mais si vous en avez vous pouvez bien entendu , utiliser des vis sans tete.
Montez la poulie de facon que le bas soit au niveau de la plaque chromée du moteur.
Les boutons de serrage ont 2 vis hex M4x20 qu'il vaut mieux coller ( epoxy).
Les pieces sont sont imprimees avec 50% de remplissage , 10 couches de 0.15 , 4 perimetres. Seul le support moteur peut avoir avoir besoin de supports (voir image).

Materiel:
Poulie GT2 16 dents pour axe de 5mm
courroie GT2 de 142 (ou 140) mm
3 vis CHC M3x16
3 vis CHC M3x8 (ou vis sans tete)
2 vis CHC M4x12
2 vis Hex M4x20
2 ecrous M4

GOOGLE TRANSLATE :

The remix of the support that I made previously did not suit me because it did not allow me to dismantle the engine quickly.
So I created this one. It allows the motor to be in a good position, which does not interfere with the movement of the telescope at altitude. It also makes it possible to remove the engine quickly or to "disengage it" to make a manual focusing.
I decided not to put a "pulling" screw to tighten the belt because ultimately it is useless, except to pull too much on the focusing axis of the telescope. The tensioning by hand is quite sufficient. (If however you want a drawing screw, I drew the pieces for and I will provide them to you on request).
For the focusing wheel I used M3 chc screws (remember to pass a tap before) but if you have you can of course use screws without head.
Mount the pulley so that the bottom is level with the chrome plate on the motor.
The tightening knobs have 2 hex screws M4x20 that are better to stick (epoxy).
The pieces are printed with 50% infill, 10 layers of 0.15, 4 perimeters. Only the engine support may need supports (see image).

Equipment:
GT2 pulley 16 teeth for 5mm axle
142 (or 140) mm GT2 belt
3 CHC M3x16 screws
3 CHC M3x8 screws (or headless screw)
2 CHC M4x12 screws
2 Hex M4x20 screws
2 M4 nuts
