Replacement roller lodgment for Sovol SH03 filament dryer.

The stock Sovol SH03 spool support has a very wide bearing wrap angle (~123° for a 200 mm spool),

which causes the filament to bind and jam — especially with smaller diameter and cardboard spools.

This lodgment set significantly reduces the wrap angle:

- 60° for 150 mm spools

- 71–75° for 120, 195–205 mm spools

What's in the set

A full assembly for one dryer chamber consists of 6 parts:

- 2× lodgment

- 2× lodgment (mirrored in slicer)

- 2× cross_member (connects the four lodgments into a rigid unit)

Since the SH03 has two chambers, you'll need two full sets (12 parts total).

Only two files are provided — mirror the lodgment in your slicer.

Alternatively, use the provided .3mf file — it contains all parts pre-arranged on the build plate in the correct quantity, including the mirrored lodgments.

Original bearings and rollers are reused — just transfer them from the stock holder.

Max spool width: 70.5 mm

Compatible spool diameters: 120–208 mm (2 kg spool support planned as a future mod)

Advantages over stock

- Much lower wrap angle → less resistance and binding

- Can be used outside the dryer as a standalone spool stand

Print settings

Since the SH03 can reach up to 90 °C internally, a high-temperature filament is required.

I printed in PC-CF. ASA should also work.

- Layer height: 0.2 mm

- Perimeters: 3 minimum

- Top/bottom layers: 5 minimum

- Infill: 25 %+
